Background

Multiple strengths of mometasone furoate/formoterol (MF/F) MDI combination therapy are under investigation as new treatments for asthma. We report efficacy/safety findings from a 3-month MF/F study in subjects with severe asthma.

Materials and methods

This was a 3-month, randomized, double-blind, parallel-group, multicenter study with a 2-3-week open-label, run-in period of mometasone furoate (MF) 400 μg twice-daily (BID). Subjects (≥12 years) were randomized to MF/F (200/10 μg or 400/10 μg BID) or MF (400 μg BID). The primary endpoint was the area under the curve (AUC) of the change in serial FEV1 (0-12 hours) for MF/F 400/10 μg vs MF 400 μg from baseline to Week 12. Adverse events (AEs) and other clinical safety measures were recorded.
